Performance requirements for high-speed anti-collision guardrails

High-speed anti-collision guardrails require high material strength, and the surface treatment of anti-collision guardrails requires anti-corrosion and anti-aging. Since guardrails are usually used outdoors, they are also highly resistant to high and low temperatures. Vehicle collision speed refers to the actual driving speed of the test vehicle measured within 6 meters before the actual collision point during the vehicle collision test.
Depending on the type of road shoulder structure, the highway corrugated anti-collision guardrail panels should adopt different structural forms. For example, when the corrugated beam is installed at the retaining wall and shoulder wall, the Gr-A-2C type can be used.
Performance requirements for highway anti-collision guardrails:
(1) Beautiful appearance. The highway corrugated anti-collision guardrail panels should be coordinated with the surrounding environment of the road, and the guardrails can be beautified through greening and other means.
(2) Strong protective ability. This means that the structure of the guardrail board must have a certain degree of compression resistance. Will not be easily broken by vehicles. Urban roads have a heavy traffic volume and accidents occur. The economic loss is also large, and it is easy to cause traffic jams, so guardrails of sufficient strength can play a certain protective role, especially on road sections with a large number of heavy-duty trucks, such as the central separation belt guardrails with strong anti-collision capabilities. A secondary collision occurred with an oncoming vehicle.
(3) Good guidance ability. This means that after the vehicle collides with the guardrail, it can be smoothly exported without rebounding too much and causing a secondary accident with the vehicle in the same direction.
(4) Good economy and land saving. While satisfying the anti-collision and guidance performance of guardrails, we should also try our best to reduce the amount of guardrail materials used to ensure economy. Therefore, guardrails with a small footprint should be used as much as possible to save space and reduce project costs.
